PEQEFICATION forming part ot Letters Patent No. 352,668, dated November 16, 1886.

.To aZZ whom, it may concern:

Be it known that I, OARL ULBRIOH, of the town of Niederlssnitz, in the Kingdom of Saxony and German Empire, have invented a certain new and luseful Apparatus for Promoting the Healthy Action of the Lungs and Heart, of which I declare the following to be a full and clear specification.

Figure l is a side view, and Fig. 2 a front View, of my iniproved apparatus with the device D L removed T T are two steps, which are connected with each other by means of a rope or its equivalent, wl1ich runs over two rollers, 1' r', so that the one step is raised in like propor-l tion to the depression of the other, which said steps glide readily up and down on the inclined surface E.

Beneath each step is an extendible pair of bellows, B B', in order to render the depression of the said step more difficult, and thus set'the entire body of the patient in like action as ensues in ascending a hill or mountain. VVhen the bellows B B' rise with the steps, they suck in fresh air through a hose, which is iu communication with the 'open air through a window or in other suitable manner. The air thus sucked in passes first into the cover of a receptacle or reservoir, l), and deposits any impurities it may contain in the wool, wadding, or fine paper layers contained in the same, and can also, if desired, be freed-fron1 moisture by means of the chlorate of lime contained in the said lid or cover, when it is requisite that the patient should inhale dry air. If it is, however, desired to inhale extract of forest-trees and oxygen, the wool, wadding, or other material is saturated with the same, so

wadding, or other material, is mixed with the same. When the air has passed 'this layer or layers of wool, wadding, or other filtering material, the same is drawn or sucked through the coiled pipe or tube F by means of the bellows, which said coiled pipe or tube is surrounded or packed in ice or cold Water when cold air is to be inhaled, or with Warm water when warm air is to be inhaled. The air now passes into the bellows B B', and is forced out of the same by each depression of a step into. the air-reservoir L, which is extended by` the said air, and the spiral or helical Springs located above the same compressed, and in this manner the advantage attained that an equable refreshing current of air is delivered through the cock or valve H and tube or pipe H' to the operator` for inhalation. This compressed air can be inhaled through a hose and mouth or nose piece. As a partial vacuum is created in the receptacle or reservoir D by the air being sucked out by the action of the bellows B B' when Operating the steps, the patient'can exhale into thin air by means of a month-piece and hose leading into the said receptacle or reservoir. If it is desired to imitate the ascension 6 3 ot' a more or less steep hill, the apparatuscan be readily adj usted to suit the same by` means of the cock or valve H. The further the cock or valve H is closed the more difficult will be the operation of the steps, and the more the said cock or valve is opened the more readilyv i will the compressed air escape and-the less power will be required to operate the apparatus. The muscularforee ex'erted in operating the apparatus is indicated by a small device, N, the lower part of which contains water or other fiuid. 'The lower half of the receptacle N is hermetically separated from the upper part, which is provided with suitable graduations. A small glass tube, which reaches almost to the cover of the indicator, passes through the horizontal partition in the said apparatus, and reaches nearly to the bottom of the lower part of the apparatus. The compressed air produced by the movement of the steps enters the recepta-cle through the small pipe or tube c above the surface of the water. The compressed air forces the water or other liquid in the lower part of the receptacle through the glass tube co into the upper part of'the said receptacle or device N in proportion corresponding to the muscular power exerted by the patient, or according to the steepness of the ascent. Each graduation rise of water in the upper part of the indicator corresponds with one of the indications or marks according to the system of Professor Dr. Oertel in his method of hill' or mountain cures. The air enters the indicator N through Ithe tube P. The rods 8 t w serve as gymnastic Ioo rack or bars, and as support or resistance when assisting the treading by the power of the arms,

the bellows B B', substantially as desoribed 15 and shown.

2. 'Ifhe combination of the Steps T T' and bellows B B' with the receptaole D, substantially as described, and shown in the accompanying drawings.

In Wtness Whereof I have hereunto signed my name in the presence of two subscribing witnesses.
